So I'm rather new to all of this. In my searching and obsessing over my newly forming Tolkien collection, I've noticed that there are two ISBNs floating around for what seem to be the Super Deluxe edition of The Children of Húrin Super Deluxe edition that was released in October of 2007. Of course, the very reliable one is the one listed as 9780007252244.

Then there is this other one that is listed only on third party sellers like AbeBooks, Ebay, and Amazon as 0007275390. The only image that ever appears with this is the same stock photo of the Super Deluxe edition, but the price is MUCH lower and the release date is listed as December of 2007.

So--does anybody know what's going on here? Is this some kind of hoax?
